We don't know what'll be the situation of us tomorrow. Food is something that is essential for our living, which means for what we earn? The very first thing is to survive and for the same food is a major thing. I've seen lot of people who had money little by little without eating good. End of the day, they spend a huge amount on medical bills. For this it is always good to understand when to eat and what to eat. Same time we should also know the limits on spending on food and where to spend, because for the same food we used to different amounts depending on the location and the comfort.
